2 thing you see a lot of growth of in high school.

Seriously though, as the end of spring training nears I thought it would be interesting to see people's views on what prospects might breakout this year and which ones might see their value drop-off a notch. The reasons for nominating a player do not necessarily have to be justified by scouting or stats, just a gut instinct is fine for this. Also, it does not have to be top-prospects being mentioned here, as long as the player is a prospect than it should be of interest.

Here is a quick list of players I compiled off the top my head.

Breakout Year

Tyson Gillies- I think he really will bust out this year in A-ball and show growth along the lines of what Michael Saunders did, with more speed, defense, and plate discipline but less power. Based off reports of him being a good citizen and hard worker in the organisation.

Mario Martinez-One of the Mariners' less heralded international signings in the past years. I see him passing DeJesus and Norriega by having improved plate discipline and growth in power.

John Mayberry- If given plenty of playing time, can be a sleeper candidate for NL ROY in my opinion. I am believer in his power that still has room for more growth and ability to handle strike zone well.

Jose Tabata- I think this year he will step up offensively in terms of contact and plate discipline, power will not come this year though.

Mitch Maier- My gut tells me he is going to experience growth in power and has he makes better contact through a better approach at the plate. Combined with good defense, will be a valuable LF/CF/RF.

Balbino Fuenmayor- I see him really having a great year in full-season ball by further reducing his K % and increasing his power #s.

Dropoff

Greg Halman- I think he has been overrated quite a bit by hitting well in the Cal league and the having a hot streak for half a season at AA. He really has issues with making contact and pitch recognition that came out in his K/BB ration in the AFL and in the WBC(SSS caveat).

Ivan DeJesus- I think he will regress more offensively while more questions about his defensive ability arise.

Jhoulys Chacin- Wear on his arm from jump in IP from 2007-2008 and advanced placement in AAA will see him struggle in a hitter friendly Colorado Springs.

Jeff Samardzija- Will return to struggles in turning his great stuff into actual results. He has potential to succeed but he is not as advanced as his numbers showed last year.

Chris Carter- Is another guy with contact issues and Cal league inflation that will regress in value in his first encounter with AA. Like Halman he has great potential but has some way to go still.
